There was a bug where players without the permission worldtp.worldtp would not be able to open the WorldTP menu. I fixed it so that they will now see the worlds that are NOT admin-only worlds.
Added a command to make a world a lobby which players will teleport to when they join the server. I also added a command to make a WorldTP spawn point which will teleport players to set position for a given world when they teleport to that world using the WorldTP menu.
